Wacky Cake

Hi Everyone, I'm so excited to share this vintage, Great Depression-era recipe for Wacky Cake recipe with you!

It's dense, sweet, fluffy, and ultra-moist - you would never believe that it doesn't have eggs, milk, or butter in it!

How To Make This Wacky Cake Recipe Vegan

This is a great cake recipe for those who have egg allergies or who can not tolerate dairy/lactose-intolerant.

We have added a frosting (with unsalted butter, confectioner's sugar, vanilla, and milk) to the top but you can easily sub out the butter for the same amount of coconut oil, the milk for the same amount of water/non-dairy, or lactose-free milk or just make a glaze instead or just sprinkle the top with confectioner's sugar - or leave it plain because it's so good by itself.

There are lots of options for this versatile cake!

Wacky Cake & My Family History

My dad told me that his mother, my grandmother, would make it for him and his siblings when they were young and she called it "Easy Cake."

I make this recipe with my kids and they (and I) love it.

It's so easy to make and fun too!

Recipe Attribution and How We Came to Make Wacky Cake

I came to make this simple cake recipe while homeschooling my kids during the Covid-19 Pandemic, one of my blogger friends Amanda from Amanda's Cookin' shared her recipe and I thought it would be a great Science/STEM recipe as well as a history lesson that reflects the times that we are in.

We changed up Amanda's recipe a little bit in terms of the topping because my daughter asked for vanilla frosting and sprinkles.

Those additions went very well on the cake.

Ingredients

Cake Batter

• 1 ½ cup all-purpose flour
• 1 cup granulated white sugar (or the same amount of confectioner's sugar)
• ½ teaspoon Kosher salt
• 1 teaspoon baking soda
• ½ cup unsweetened cocoa powder
• 6 tablespoons Canola oil (or same amount vegetable or flavorless oil)
• 1 tablespoon white vinegar
• 1 teaspoon pure vanilla extract
• 1 cup cold water

Buttercream Frosting

• 1 tablespoon unsalted butter
• 1-2 tablespoons milk (or substitute the same amount non-dairy milk or water), amount depending on how thick you want the frosting
• 1 cup confectioner's sugar
• ⅛ teaspoon (pinch) of Kosher salt, optional (to counteract the sweetness)
• ½ teaspoon pure vanilla extract
• Sprinkles amount to taste

How Does Wacky Cake Rise/Leaven?

The distilled white vinegar reacts with the baking soda (not baking powder!) when you mix it and it causes the cake batter to rise when baking.

It produces a beautifully moist, densely thick, fluffy cake.
